The Lectric XP4 is the better bike at the same $999 price, with a torque sensor, hydraulic brakes, and a color display the XP 3.0 never had. If you already own an XP 3.0 that runs fine, keep riding it. But if you are choosing between them today, or your XP3 is tired, the XP4 wins every category that matters and the 750w long-range version ($1,299) adds 85 claimed miles for commuters who need it.

The torque sensor is the real upgrade
The XP 3.0’s cadence sensor delivers power like a light switch: pedal, wait a beat, surge. The XP4’s torque sensor reads how hard you press and matches it instantly, which makes the bike feel like your legs got stronger instead of like a motor is shoving you. It is the single biggest ride-quality difference between the two generations, and it is the feature you cannot retrofit. In our XP4 review we called it the best folding e-bike under $1,500, and the torque sensor is most of the reason.
The rest of the XP4 package stacks small wins on top: stronger 602 hydraulic calipers, a bright color display, cleaner cable routing, and a 750w long-range version with an 840Wh battery that claims 85 miles. The XP 3.0 we reviewed was the value king of its day, but every one of its weak points got addressed.
Keep your XP 3.0 if
- It runs fine and you ride casually; the XP4 is better, not life-changing
- Your battery still holds a healthy charge
- You would rather put $999 toward your next bike in a few years
Buy the XP4 if
- You are buying your first folding e-bike (no contest, get the XP4)
- Your XP3 battery is fading; a replacement pack costs a real chunk of a new XP4
- You pedal more than you throttle; the torque sensor changes the experience
- You need real range: the 750w long-range claims 85 miles for $1,299
Frequently asked questions
What is the difference between the Lectric XP3 and XP4?
The XP4 adds a torque sensor, upgraded hydraulic brakes, a full-color display, and a redesigned frame at the same $999 starting price. A 750w long-range version with an 85 mile claimed range is available for $1,299.
Is the Lectric XP4 worth upgrading to from the XP 3.0?
If your XP 3.0 works and you mostly use the throttle, no. If your battery is fading or you pedal a lot, yes; the torque sensor alone transforms the ride.
Does the XP4 still fold like the XP3?
Yes. The XP4 keeps the folding design in step-over and step-thru frames. At 69 lb it is about 5 lb heavier than the XP 3.0, so plan for that if you carry it upstairs.
